Description
Technical field
The present invention relates to a kind of processing method of fabric, be specifically related to a kind of afterfinish method of automobile inner decoration facing, the automobile inner decoration facing after the arrangement is the nano-negative ion fabric.
Background technology
In recent years, along with China's auto output and class constantly promote, the aggravation of market competition, requiring automobile to possess the vehicle environment that collection is comfortable, healthy, environmental protection is one decorates, contain toxic gas in the new car inner decoration material, mainly comprise benzene, formaldehyde, acetone, dimethylbenzene etc., can make poisoning symptoms such as having a headache, weak appears in the people; Harmful substances such as the carbon monoxide that automobile engine, A/C evaporator produce, gasoline smell, amine, nicotine, bacterium all can make the air quality in the compartment descend.Therefore, domestic automobile manufacturer has also accelerated the renewal speed of automobile inner decoration facing, to satisfy requirement of client.
The anion textiles becomes the main flow and the exploitation focus in weaving market as a kind of emerging grade textiles.Ultra-fine anion powder particulate that this textiles is compound, because the permanent generation weak current of this negative ion powder physical efficiency, when the anion textiles (vibrates for a long time, jolts, rubs) under the excited target condition, can promote surrounding air generation ionization, thereby generation negative aeroion, and keep certain air-anion concentration, thereby have clean air, eliminate pernicious gas, functions such as antibacterial bacteriostatic, radiation infrared, electromagnetic radiation resistant, and when air-anion concentration greater than 2000/cm
3The time, can also regulate human physiological functions, have activating cell, allaying tiredness, enhancing resistance against diseases, improve health-care functions such as allergic constitution.Therefore, this anion textiles has been widely used in aspects such as clothes, indoor article and sports goods, is subjected to popular like and pursuing.
Yet, existing anion textiles is not suitable for directly using as automobile inner decoration facing, this is because there is following shortcoming in it: the anion powder particulate on the 1. existing anion textiles and fabric to combine fastness not high, when the automobile long-time running be in jolt and Frotteurism under, be prone to the situation that the vibration of anion particulate is dropped, had a strong impact on it and produced the function of negative aeroion, service life is short; 2. the anion powder microparticulate on the existing anion textiles is relatively poor, and it is high that the air-anion concentration of generation is owed, and is difficult to the negative ion concentration that keeps higher in the air ambient of limited bulk, can't give full play to unique health-care effect.
Summary of the invention
The preparation method who the purpose of this invention is to provide a kind of back arrangement nanometer negative ion automobile inner decoration facing, the nano-negative ion lining that it obtains not only has excellent vibrostability and ABRASION RESISTANCE, can also discharge the negative aeroion of high concentration, be highly suitable for the automotive trim field.
To achieve the above object of the invention, the technical solution used in the present invention is: a kind of preparation method of nanometer negative ion automobile inner decoration facing comprises the following steps: successively
(1) anion material is processed as nanometer grade powder, described anion material is a tourmaline;
(2) in deionized water, add described nano-negative ion powder, through high-speed stirred, add dispersant Sodium Polyacrylate and silane coupler down at 40～50 ℃, the mass ratio of described deionized water, nano-negative ion powder, dispersant, coupling agent is 100: 8～15: 3.0～3.5: 3～4, and described silane coupler is selected from vinyl silanes, amino silane, methacryloxy silane, hydrosulphonyl silane or urea groups silane;
(3) more above-mentioned solution is carried out ultrasonic dispersion treatment, obtain the nano-negative ion finishing agent;
(4) with 20～50 times of above-mentioned nano-negative ion finishing agent dilutions, employing is soaked-is rolled-baking technology, automobile inner decoration facing two is soaked two and rolls in above-mentioned nano-negative ion finishing agent dilute solution, pick-up rate 70～80%, again in 80～90 ℃ of preliminary dryings, 150～180 ℃ bake, and promptly obtain described back arrangement nanometer negative ion automobile inner decoration facing.
Above, the anion material that adopts in the step (1) is a tourmaline, it has pyroelectricity and piezoelectricity, when temperature and pressure have minor variations, can cause electrical potential difference between the tourmaline crystal, promote surrounding air generation ionization, the electron attachment that detaches makes it be converted into negative aeroion in contiguous water and oxygen molecule, and this material can constantly discharge anion, keep dynamic equilibrium, keep air-anion concentration.
Above, described step (1) can adopt micropowder processing method such as air-flow crushing technology that tourmaline is processed as nanometer grade powder; The soaking-roll of described step (4)-baking technology is prior art, is generally used for that fabric is carried out the back arrangement and handles.
Further technical scheme, the viscosity average molecular weigh of the Sodium Polyacrylate in the described step (2) is 3000～5000 dalton, has better dispersive property and viscosity.
Further technical scheme, the particle diameter of the nanometer grade powder that obtains in the described step (1) distribute and are mainly 40～60 nanometers.
The nano-negative ion lining that the present invention obtains mainly as automobile inner decoration facing, also can be used as vehicles inner decoration materials such as aircraft, passenger steamer, also can be applicable to aspects such as clothes, indoor article and sports goods.
Principle of the present invention is: earlier the anion material tourmaline is made into nano_scale particle, adopt and stir, the method that the physics dispersion method of ultrasonic dispersing combines with the chemical dispersion method that adds the Sodium Polyacrylate organic dispersing agent is with uniform and stable being dispersed in the aqueous solution of nanoparticle, meanwhile, because Sodium Polyacrylate has good adhesive effect, be used silane coupler again, between nano-tourmaline particulate and fabric, erect " molecule bridge ", in conjunction with soak-roll-baking technology the nano-tourmaline particulate is evenly disperseed and strong bonded on fabric, obtain final back arrangement nanometer negative ion automobile inner decoration facing; In addition, the preferred viscosity average molecular weigh of the present invention is 3000～5000 daltonian Sodium Polyacrylates, and cooperates corresponding silane coupler, the inner decoration facing that obtains to have excellent vibrostability and ABRASION RESISTANCE, and can discharge the negative aeroion of high concentration.
Because the employing of technique scheme, compared with prior art, the present invention has following advantage:
1. because the nano-negative ion finishing agent of the present invention's preparation has adopted the Sodium Polyacrylate with excellent bonds effect, and cooperate corresponding silane coupler, thereby utilize nano-tourmaline particulate on the fabric that arrangement obtains behind this solution can strong bonded on fabric, under vibration and Frotteurism condition, the situation that particulate comes off can not occur, be suitable for as automotive interior material.
2. because the method that the nano-negative ion finishing agent of the present invention preparation has adopted the physics dispersion method of stirring, ultrasonic dispersing to combine with the chemical dispersion method of interpolation Sodium Polyacrylate dispersant simultaneously, and added silane coupler, thereby utilize the nanoparticle dispersiveness of putting in order on the fabric that obtains behind this solution good, be nano level owing to the tourmaline anion material again, so this fabric can discharge the negative aeroion of high concentration.
